timer_settime64

arm/disarm and fetch state of POSIX per-process timer

sys_timer_settime(timer_t timer_id, int flags, const struct __kernel_itimerspec *new_setting, struct __kernel_itimerspec *old_setting)

register	value
`eax`	409, the syscall number
`ebx`	timer_t timer_id
`ecx`	int flags
`edx`	const struct __kernel_itimerspec *new_setting
`esi`	struct __kernel_itimerspec *old_setting
`eax`	the return value

Then run int 0x80 to enter the kernel.

Same syscall on other architectures
